CLOSURE.

- Application filed April as, 1922; Serial no. 556,691.

To all whom it may concern.

Be it known that I, NIXON LEE, a citizen of the United States, and aresident of the borough of Brooklyn, in the county of Kings and State ofNew York, have invented certain newv and useful Improvements in C-sures, of which the following is a specification, reference being madeto the accompanying drawings, forming a part thereof.

My invention relates to closures used for sealing the openings incontainers, jars or bottles in which the closure is adapted to berepeatedly applied to and removed from the container, and furthermore totightly seal the container when the closure is aflixed and locked insealing position, even after repeated applications and removals.

The objects of my invention are, among other things, to provide animproved closure structure of this type of container and closure wherebya more perfect seal and re-seal is secured for such improved closure; toprovide a closure with a depending skirt portion and a plurality ofinwardly extending lips to engage with radially projecting lugs on thecontainer in which the leading edges of the lip portions shall be formedto engage with progressively increasing ressure the under surfaces ofthe lugs to raw down the closure upon the rim of the containeropenings.- Furthermore I also provide a novel stop end for each of thelips to coact with the lugs to limit the rotation of the closure inthe-seating direction which 85 stop end at the same time tends to drawdown the cap of the closure upon the rim of the container opening with adistributed, substantially uniform pressure, thereby furnishing aneffective closure seal which can L be repeatedly used for rescaling thecontainer opening after the closure has been initially removed.

With the above and other objects in view, my invention comprises thenovel construetion, combination and arrangement of parts to behereinafter specifically described and then particularly pointed out inthe appended claims.

I attain the foregoing advantages b the closure shown in theaccompanying raw in s in whichig. l is a side elevation of the glasscontainer showing a preferred embodiment of my improved closure cap indotted lines; Fig. 2 is an enlarged bottom plan view of the closure; Y

Fig. 3 is an enlarged detail view;

Fig. 4 is an enlarged fragmentary bottom direction of locking andsealing the closure;

Fi 8 is an enlarged perspective vlew showm in detail the construction ofthe stop en of the closure; and

Fig. 9 is an enlarged vertical sectional view showing the closure lockedon the container mouth.

Similar numerals refer to similar parts throughout the several figures.

Referring more particularly to Figs. 1 and 2, the container 10preferably formed of glass or other friable material, is of any referredshape or form, and has formed immediately below the mouth 11 on theexterior walls of the container a plurality of radially-projectingequally spaced-apart lugs 12, thenumber varying according to the size ofthe container. These lugs 12 have rounded ends 13' and a substantiallyflat horizontall disposed underrsurface let as shown in i 1 and 9 toformthe locking means for t e closure with the container; each roundedend .13 therefore provides a progressively projecting under edge tocoact with the stop end of the inturned lips as-will hereinafter bedescribed. I

The closure 15 proper is preferably formed of a resilient sheet-metalandcomrises the circular top or cap'16 from which epends the annular skirtrtion'17 which 'is usually knurled. The skirt 17 has s aced the skirtsand segmental in shape as shown in i apart inturned lips 18 integral witFig. 2, and somewhat longer than the lugs -panding 12. The leading end19 of each of the lips 18 is substantially square and bent downwardly toform the inclined depressed portion 20 which is adapted to initiallyengage the rounded ends13 of the lugs when the closure 15 ispreliminarilyrotated toward.

locking position as shown in Fig. 7.

' The stop end of the lips 18 is formed as shown in detail in Fig. 8 bybending the lip end to form the inclined fiace 21 and diagonallydisposed brace 22, the face 21 being adapted to engage with the underouter edge of the rounded end 13 of the lug 12 to stop the rotatingmovement of the these stop faces 21 when pressed against the undercorners of the lug ends 13, the edges of which are progressivelyprojecting as shown in Fig. 4. I

The 0 eration of my improved closure is substantially as follows: Theclosure 15 is set on the container mouth 11 so that the lugs 12 aredisposed between the several lips 1-8 with the lining or pack 23 restlngon the circular rim 24. Then this closure is twisted or horizontallyrotated on the container mouth 11 so that the depressed ends 20 engagethe leading ends 13 of the lugs 12 and guide the lips 18 to slide alongthe under surfaces 14, as shown in the righthand end of Fig. 7.. Thenthe continued rotation of the cap causes the several lips 18 to ridealong the under surfaces 14 of the lugs 12 until the face 21 engages theunder corner of the end 13 which stops the closure rotation. Then a fin'al twist given to the closure 15 will cause the faces 21 to slide intofirm locking engagement with the under outer edges of the lugs 12tending to slightly spread the skirt 17 outwardly as shown in Figs. 4and 5. The tension in the skirt 17 resists such spreading andeffectually prevents further rotation of the cap. The effect of suchcomplementary spring action between the ca 16 and exskirt 17 is that thelining or pack 23 is firmly forced down and compressed on the rim 24from points e ually spaced apart on the circumference o the closure, andprovides a hermetic seal of uniform tightness throughout the annularseating of the closure.

It is manifest that my improved closure may be readily removed andafterwards replaced on the container to attain resealing, and that Ihave embodied in my container closure structural features which add tothe effectiveness of the seal under different conditions of usage.
